Method and apparatus of curing concrete structures

A method of curing concrete comprising:

• a. conducting electrical energy through a heating component wherein at least a portion of the heating component is within concrete;
• b. achieving a first temperature of concrete;
• c. changing the amount of electrical energy so that the concrete achieves a second lower temperature and temporarily achieves a maximum rate of cure;
• d. continuing steps a through c to control a rate of cure of the concrete.
